CVE-2019-17221

Name of the Vulnerable Software and Affected Versions PhantomJS versions 2.1.1 and earlier

Description The issue allows for arbitrary file read, demonstrated by an XMLHttpRequest for a file:// URI. It exists in the page.open() function of the webpage module, which loads a specified URL and calls a given callback. An attacker can supply a specially crafted HTML file as user input to read arbitrary files on the filesystem. For example, if page.render() is the function callback, this generates a PDF or an image of the targeted file.

Recommendations As a temporary workaround, consider disabling the page.open() function until a patch is available. Restrict access to the webpage module to minimize the risk of exploitation. Avoid using the file:// URI in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
